CUTTING AND PERFORATING ATTACHMENT FOR PRINTING-MACHINES.

Specification of Letters Patent.

Application filed April 1, 1903.

Patented Oct. 27, 1908.

Serial No. 150,520.

To all whom it may concern:

Be it known that I, GEORGE F. MoADAMs, a citizen of the United States, and resident of the borough of Brooklyn, in the city and State of New York, have invented a new and useful Improvement in Cutting and Perforating Attachments for Printing-Machines, of which the following is a specification.

My invention relates to an improvement in cutting and perforating attachments for line printing machines and has for its prin* cipal object to accomplish the lining, perforating and cutting in one operation.

A further object is to provide a structure in which the devices for cutting and perforating are driven by the driving shaft of the printing machine and arranged to receive the paper as it leaves the printing rolls for insuring the most accurate results in cutting and perforating the paper with respect to the lines printed thereon.

A further object is to provide an attachment as above set forth in which the perforating disk rolls and their impression rolls may be adjusted to any desired position laterally of the machine.

A further object is to provide means for adjusting the cutting rolls laterally of the machine for severing the paper as it leaves the line printing rollers.

Heretofore it has been common to cut and perforate the paper after it has been removed from the line printing machine and it has been found to be extremely difficult to properly adjust the paper and feed it so that the ruled lines and the severing and perforating lines will corres 0nd to a nicety. This undesirable feature as been eliminated by my improved attachment which will be hereinafter fully described.

A practical embodiment of my invention is represented in the accompanying drawings, in which Figure 1 represents a side view of a line printing machine with my improved cutting and erforating attachment applied thereto; only so much of the machine being illustrated as will give a clear understanding of the position and operation of my invention, Fig. 2 is an end view of the same, Fig. 3 is an enlarged longitudinal central section through one of the perforating disk carrying sleeves and its adjacent parts, Fig. 4 is a transverse section taken in the plane of the line A-A of Fig. 3, and Fig. 5 is an enlarged cross section through the sheet cutters.

The side frame of the line printing machine is denoted by 1 and the main drive shaft 2 of the machine is mounted in suitable bearings therein. This shaft 2 is provided with a friction driving pulley 3 which engages the peripheries of friction driving pulleys 4 and 5 of the impression roll 6 and printing roll 7, which pulleys 4 and 5 in turn drive by friction the pulleys 8 and 9 of the line printing roller 10 and impression roll 11. The usual ink fountains 12 and 13 serve to supply ink to the disks upon the rolls 7 and 10 in any well known or approved manner.

The cutting mechanism for severing the paper is constructed and arranged as follows :Each side frame 1 of the machine is provided with a bracket 14 secured thereto immediately to the rear of the rolls 7 11. This bracket 14 is provided with an elongated vertical recess 15 for receiving the end bearings of the shafts 16 and 17, which sup port the cutting and perforating devices. The shaft or roller 16 is provided with a longitudinal groove 18 therein. A sleeve 19 may be adjusted along the shaft or roll 16 to the desired point and there secured by a set screw 20 which enters the groove 18 and serves to prevent the rotary movement of the sleeve 19 with respect to the shaft or roll. This sleeve 19 forms one member of the cutter, one of its end edges being formed for this purpose. The yielding member of the cutter comprises a cylindrical sleeve 21 having a sliding engagement with the shaft or roll 17, the said sleeve overlapping the face of the member 19 of the cutter and being held yieldingly against the same by means of a coil spring 22 surrounding the shaft or roll 17 and interposed between the said sleeve 21 and an adjustable collar 23 fixed to the shaft or roll 17 by a set screw 24. This shaft or roll 17 is also provided with a longitudinal groove 25 and the yielding cutting member or sleeve 21 is held against rotary movement with respect to the shaft or roll by being provided with a tongue 26 which enters the said groove 25. Theset screw 24 of the collar 28 also enters the groove 25 to prevent the rotary movement of the collar with respect to the shaft or roll.

The perforating device is constructed and arranged as follows :The sleeve 27 is mounted on the shaft or roll 16 and is adjustably secured at any desired point thereon and at the same time held against a rotary movement with respect to the shaft or roll by means of a set screw 28 which enters the groove 18 in the said shaft or roll. The sleeve 27 is provided at one end with a reduced cylindrical portion 29 having a screw threaded end 30. A perforating disk 31 is held in position upon the reduced portion 29 of the sleeve 27 with its teeth projecting a short distance beyond the periphery of the sleeve. In the present instance, I have shown this disk as being secured in position by means of a collar 32 fitted to the periphery of the reduced portion 29 of the sleeve, which collar is held pressed against the perforating disk 31 by means of a nut 33 which engages the screw threaded portion 30.. Two sleeves 34, 35, are secured in the desired position upon the shaft or roll 17 so as to leave a small peripheral groove 36 between them for the reception of the projecting periphery of the perforating disk 31. I have shown set screws 37, 38, which enter the groove 25 in the shaft or roll 17 for securing the sleeves 34, 35, in the required position on the shaft and also serve to prevent the sleeves from rotating with respect to the said shaft.

The sleeve 27 which carries the perforating disk rests upon the periphery of the sleeve 34 and the collar 32 rests upon the periphery of the sleeve 35, the weight of the shaft or roll 16 being thus taken upon the shaft or roll 17.

To prevent the paper from tending to wrap around. the shaft or roll 16 as it leaves the perforating disk, I provide the sleeve 27 with a peripheral groove 39 for receiving a cord 40 which passes around the sleeve 27 and leads rearwardly to another roll not shown herein.

In the accompanying drawings, I have shown two of these perforating devices located in close proximity to each other and one of the cutting devices.

It is to be understood, however, that I may employ any number of perforating and cutting devices and may locate them at the required positions on their shafts or rollers to perforate and cut the paper as may be desired.

The shaft or roll 16 is positively driven from the driving shaft 2 of the printing machine in the present instance by means of a belt 41 passing around a drive pulley 42 on the shaft 2 and a pulley 43 on the shaft or roll 16.

It will be seen that by the construction herein set forth, I am enabled to accurately adjust the cutting and perforating devices with respect to the paper and the lines printed thereon. Furthermore, this attachment obviates the necessity of an extra handling of the paper and the consequent expense there'- for. It will also be seen that by mounting the perforating and cutting devices upon the same shafts, I am enabled to produce a very simple and compact device.

It is evident that changes might be resorted to in the form, construction and arrangement of the several parts without departing from the spirit and scope of my invention; hence I do not wish to limit myself strictly to the structure herein set forth, but

I/Vhat I claim is In a line printing machine, the combination with the disk rolls, of two shafts mounted adjacent to the disk rolls and having longitudinal grooves along the same, one member of a paper cutting device and one member of a perforating device being mounted on one shaft and the other member of the paper cutting device and the other member of the perforating device being mounted on the other shaft, whereby all two devices are fitted to simultaneously receive the paper from the disk rolls, the said devices being so formed as to act as supports for holding the paper flat as it is being operated upon, set screws carried by the said device members arranged to enter grooves in the shaft for securing the members of the devices to the shaft at any desired position along the same and means for preventing the paper which is being operated upon from wrapping around the shaft as it leaves the perforating disk.

In testimony, that I claim the foregoing as my invention, I have signed my name in presence of two witnesses, this 20 day of March 1903.
